XFOR: MSMI Crashes Logging NDR Event, Generates Event ID 2380

• Microsoft Exchange Server versions 4.0 and 5.0

SYMPTOMS

The Microsoft Exchange Server Microsoft Mail interchange (MSMI) stops and may log the following events in the Windows NT Event Viewer Application log:

   MSExchangeMSMI Event ID 2380:
   Source: MSMI
   Category: SessionError
   Description: A memory access violation occurs that prevents further
   processing of a messsage

   MSExchangeMSMI Event ID 10003:
   Source: MSMI
   Category: SessionError
   Description: Fatal Assert: File sfsems.cpp line 837.  Mailer thread

CAUSE

The MSMI is attempting to log an event for an NDR of a message with invalid sender and recipients.

WORKAROUND

Resetting the INQUEUE3 Key and Mbg file on the shadow post office will allow the MSMI to restart, but will result in the loss of any messages in the queue.
